Pool Area Etiquette

I encountered this sign some time ago, but was reminded of it while contemplating the benefits of joining our local indoor pool so that I could exercise without risk of tripping and falling into traffic: 

Note to self:  If it hadn't happened...they wouldn't have needed to write it on a sign.

Clearly, "Do not run" and "No diving" have been superseded by "Do not swallow the pool water" and "Change diapers in a bathroom and not poolside".

Again.  If it hadn't happened, they wouldn't have needed to...well...you get the rest.

Mmmyeah.  I think I may stick with oncoming traffic.
